无法使用 dockerized django 项目运行 vscode 的调试器

每次运行调试器时，都会发生很多事情，但并不是我所期望的。

我正在用docker-compose up运行一个项目

检查本地主机后端是否正常。它倒下了。有趣的是，容器正在运行，因为我与vscode的远程容器相连。

已安装debugpy库。

运行调试器的第一种方法是在调试控制台中显示这样的信息：

Attached!
System check identified some issues:
WARNINGS:
workflow.State.additional_values: (fields.W904) django.contrib.postgres.fields.JSONField is deprecated. Support for it (except in historical migrations) will be removed in Django 4.0.
HINT: Use django.db.models.JSONField instead.
Operations to perform:
Apply all migrations: accounts, auth, contenttypes, files, mambu, otp_totp, sessions, token_blacklist, workflow, zoho
Running migrations:
No migrations to apply.

然后它就倒下了。后端也出现故障。

第二次尝试：

Attached!

WARNINGS:
workflow.State.additional_values: (fields.W904) django.contrib.postgres.fields.JSONField is deprecated. Support for it (except in historical migrations) will be removed in Django 4.0.
HINT: Use django.db.models.JSONField instead.
Zoho Configuration failed, check that you have all variables ZOHO_TOKEN_URL, ZOHO_REST_API_KEY, ZOHO_CURRENT_USER_EMAIL

它关闭了，但后端启动了-我可以登录等

第三次尝试以这样的错误connect ECONNREFUSED 127.0.0.1:5678结束。

有什么建议吗？

代码：

管理员.py

#!/usr/bin/env python
"""Django's command-line utility for administrative tasks."""
import os
import sys
def initialize_debugger():
import debugpy
debugpy.listen(("0.0.0.0", 5678))
debugpy.wait_for_client()
print('Attached!')
def main():
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "xxx.settings")
try:
from django.core.management import execute_from_command_line
except ImportError as exc:
raise ImportError(
"Couldn't import Django. Are you sure it's installed and "
"available on your PYTHONPATH environment variable? Did you "
"forget to activate a virtual environment?"
) from exc
execute_from_command_line(sys.argv)
if __name__ == "__main__":
initialize_debugger()
main()
